A night of big reality on the Big Four sees big percentage drops for the current competition king — and a slew of soft entries.

It may have been up significantly, week to week, but the spring finale of The Voice clocked a series low for a season ender. Wrapping its run a month earlier than the comparable cycle in 2013, the average 3.3 rating with adults 18-49 marked a 25 percent hit.

NBC still easily won the night in the key demo, and The Voice also logged 11.6 million viewers -- shy of the night's most watched program, Dancing With the Stars.

The ABC ballroom competition was also down from last year's spring finale, averaging a 2.4 rating with adults 18-49, but it was only off by three-tenths of a point. The show took in 14.9 million viewers.

American Idol aired its performance finale to an average 1.7 rating in the key demo. With an especially heavy amount of reality competition on the night, it suffered a 43 percent drop from the penultimate episode last season.
